Possible problems created by "GOODCHARS" extension when moving from compiled source to package.

[Eric Luyten]

Hello,



When moving from U Washington IMAP to Cyrus more than ten years ago I 
stumbled upon

a limited number of mailbox names containing characters not allowed in 
Cyrus as per the

GOODCHARS definition in imap/mboxname.c


I added    ()*?;[]%<>    to this string, tested, ran into no issues, so 
we went into production

with this change.


We are now planning a Cyrus upgrade, a move to Debian based Cyrus 
package is likely.

This will however imply adhering to the default GOODCHARS definition as 
of then.


Q : it's okay for us to have the users being unable to create new 
mailboxes with the now

       "illegal" chars but are we likely to run into trouble with 
existing mailbox names ?



Corollary question : is there a Cyrus 3.0.x package our for any Linux 
distro ?

I find a packaged 2.5.10-3 for Debian 9  "Stretch"



Thx,
